LD39020TPU32R Description

Short technical summary and product information.

The LD39020TPU32R from STMicroelectronics is a linear voltage regulator designed for efficient power management. It delivers a stable 3.2V output voltage with a maximum output current of 200mA. The device operates with an input voltage range up to 5.5V and exhibits a low dropout voltage of 0.35V at 200mA.

 

Key electrical characteristics include a quiescent current of 40 µA and a high Power Supply Rejection Ratio (PSRR) ranging from 80dB to 55dB across the 1kHz to 100kHz frequency range. Protection features such as over current, over temperature, and soft start are integrated for enhanced reliability.

 

This regulator is housed in a compact 4-DFN (1x1) package, specifically a 4-XDFN exposed pad, making it ideal for space-constrained applications. It is designed for surface mounting and operates across a wide temperature range of -40°C to 125°C (TJ).
